Patent number: 7160618Abstract: Method of improving humidity resistance in a coated article (19) comprising a carbon-carbon composite component (10), a graphite component (10), or a ceramic matrix composite component based on carbon fibers and/or graphite (10). The component (10) is preferably configured as an aircraft landing system brake disc. The method includes the steps of: (A) providing a carbon-carbon composite component (10), a graphite component (10), or a ceramic matrix composite component based on carbon fibers and/or graphite (10); (B) covering the component (10) with a phosphorus-containing antioxidant undercoating (11) having a thickness of approximately 1–10 mil; and (C) covering the resulting undercoated component (10, 11) with a boron-containing glass overcoating (12) having a thickness of approximately 1–10 mil. The overcoating includes 20–50 wt-% alkali or alkaline earth metal silicates, 3–25 wt-% alkali metal hydroxide, up to 10 wt-% boron nitride, and one or both of 5–40 wt-% elemental boron and 5–40 wt-% boron carbide.Type: GrantFiled: July 6, 2004Date of Patent: January 9, 2007Assignee: Honeywell International Inc.Inventors: Terence B.

Patent number: 6886668Abstract: Antioxidant coating compositions containing 10-75 wt % H2O, 20-65 wt % H3PO4, 0.1-20 wt % alkali metal mono-, di-, or tri-basic phosphate, 0-2 wt % hydrated boron oxide, 0-18 wt % KH2PO4, 3-10 wt % of a transition metal oxide, and 0-20 wt % hydrated manganese phosphate, 0-25 wt % Al(H2PO4)3, and 0-10 wt % Zn3(PO4)2, provided that at least one of Al(H2PO4)3, Zn3(PO4)2, and hydrated manganese phosphate is present. Also, brake discs made from carbon composite articles having their surface treated with certain antioxidant coatings. During a manufacturing process, carbon matrix 15 of brake disc 11 is covered on its outer and inner edges with antioxidant layers 19 and portions of the working surface of brake disc 11 may also be covered with antioxidant layers 13, potentially decreasing the fitness of the brake disc for service. In accordance with this invention, brake disc 12 is manufactured from brake disc 11 by the removal from its working surface of antioxidant layers 13.Type: GrantFiled: December 18, 2003Date of Patent: May 3, 2005Assignee: Honeywell International Inc.Inventors: Manuel G.
